Subject [jira] [Commented] (QPID-6717) selector can match incorrectly due to different type for values
Date Wed, 02 Sep 2015 21:06:45 GMT

    [ https://issues.apache.org/jira/browse/QPID-6717?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14728027#comment-14728027

Gordon Sim commented on QPID-6717:
----------------------------------

Yes, it does work because 've>=vl && ve<=vu' will always be false if ve is non-numeric.

> E.g. a selector "x BETWEEN 1 AND 10" would match for a value of x="foo", because of the
way the logic is implemented for the between expression, or a selector "x NOT IN ('a', 'b',
'c')" would match where x=1, though it should not due to the type mismatch.
> From JMS spec: "Only like type values can be compared. One exception is that it is valid
to compare exact numeric values and approximate numeric values"
